Title: Improvements relating to magnetostrictive and piezo-electric vibratory systems
IPC: H03B5/30
Filed: 1928-01-03
Abstract: 311,004. Pierce, G. W. Jan. 3, 1928. Divided on 283,116 under which a Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 4, 1928. Regulation, automatic. -Magnetostricfive vibrators comprising a magnetic core surrounded by a coil carrying alternating current are employed in association with microphones or like variable resistances as frequency stabilizers for A.C. machines and circuits. In the system shown in Fig. 2, an electromotor 53 drives an A.C. generator 55, which supplies current to a load 57 and to the exciting coil 10 of a vibrator 2. At each end of the core an inertia switch is mounted, and vibration of the core increases the average resistance at the switch contacts by intermittently opening them against the pressure of springs 45. The switch contacts are in circuit with a battery and relay 29. When the frequency of the core is suitably chosen, any increase in speed of the generator 55 increases the vibrations of the core, and reduces the current in the local circuit, causing the armature 31 to drop, and by suitable means to slow down the motor 53 to normal. Specification 313,031 is referred to.

Title: Improvements in and relating to modified aminotriazine-formaldehyde resin compositions
Inventor: BROOKES ALFRED
IPC: C08G12/46
Filed: 1957-03-08
Abstract: Compositions comprising aminotriazine-aldehyde resins are modified by one or more polyethylene glycols of formula HOCH2CH2-(OCH2CH2)n(H, in which n is 15 to 170, to give products of improved flow and fusibility characteristics.  The preferred aldehyde for the aminoplast resin is formaldehyde but other aldehydes e.g. benzaldehyde may be used if desired.  Melamine is the preferred aminotriazine although ammeline, melam and benzoguanamine may also be used.  The ratio of aldehyde to aminotriazine generally ranges from 0,43 to 2 aldehyde radicals per amino radical of the aminotriazine and the amount of polyethylene glycol employed ranges from 2% to 30% by weight of the weight of the aminoplast resin or resin forming agent used.  The polyethylene glycols may be added as modifiers in the initial condensation process to form the aminotriazine-aldehyde resin, or at any convenient stage after partial condensation. Examples are given of laminates prepared from glass fabric impregnated with aqueous resins prepared from either a mixture of formaldehyde, melamine and a commercial polyethylene glcycol or a mixture of a commercial melamine-formaldehyde resin and a commercial polyethylene glycol. If desired the aminoplast component may be alkylated with alcohols containing 1 to 3 carbon atoms.

Abstract: 1,190,532. Milking appliance. ZERO MFG. CO. 17 Feb., 1968, No. 7886/68. Heading A1M. [Also in Divisions F2 and G1] Milking apparatus comprises a milk receptacle 60 for receiving milk from teat cups 10, a first source of vacuum connected to the receptacle and teat cups, a second source of relatively higher vacuum connected to an outlet 74 adjacent the bottom of the receptacle for transferring milk to a reservoir (not shown) via a conduit 72, a valve 31 for separating the sources of vacuum and a milk measuring container 86. The lower vacuum is applied to the receptacle 60 and the tea cups via pipes 16-18 whilst the relatively high vacuum is applied to the pipe 32 delivering the milk to the reservoir. The level of the milk in the receptacle 60 rises until the valve 31 is lifted thus allowing the bulk of the milk to flow to the conduit 72 via a pipe 64 and a proportion of the milk to flow through a conduit 70 via a pipe 62. The container 86 is connected to the conduit 70 via a conduit 85 to prevent siphoning action and a hook shaped conduit 84 which, by engaging a peg 82, raises or lowers the container 86 in order to correctly calibrate the container. An opening 96 in the bottom of the container is closed by a valve 95 so that on lifting a tab 92 air enters the container via a hole 94 thus causing the valve to drop and allowing a sample of milk to enter a cup 102. Milk is removed from the container by manually lifting it above the pipe 32 so that the milk drains through a tube 90. In a modification, the conduits 62, 70 are omitted, the entire milk from the receptacle flowing through a double valve incorporating a needle valve which lifts from its seating by an amount proportional to the volume flow to enable a proportion of the milk to pass to the measuring container.

Title: Improvements in processes for the preparation of the mononitrides of the rare earth metals and of yttrium
Inventor: ANSELIN FRANCOIS
IPC: C01B21/06
Filed: 1964-02-26
Abstract: Mononitrides of the rare earth metals and of yttrium are prepared by nitriding rare earth or yttrium metal in massive form, the masses having been previously subjected to a surface hydriding, the process being similar to that disclosed in the parent Specification.  The surface hydriding preferably takes place at a temperature starting from 350 DEG  C.  For small metal samples, and for large samples of yttrium and of the rare earth metals which have relatively high melting points, the hydriding and nitriding may take place in one stage in the presence of both hydrogen and nitrogen; for large samples, especially those of the rare earth metals which have relatively low melting points, for example lanthanum, the masses may first be subjected to surface hydriding in the presence of hydrogen alone and subsequently be subjected to nitriding in the presence of both hydrogen and nitrogen.  After nitriding by either method, the masses may be crushed and subjected, if the nitriding is not complete, to further nitriding.

Filed: 1949-03-24
Abstract: 658,554. Frequency modulation. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. March 24, 1949, No. 8120. Convention date, April 2, 1948. [Class 40 (v)] [Also in Group XL (a)] Relates to receivers for frequency-modulated waves in which the received wave is demodulated by applying it to deflecting means associated with an electron beam tube to cause the beam to traverse a number of collector segments in a closed path, the shape of which depends on the frequency, and consists in providing means for centring the beam when no received wave is applied. As shown, the F.M. wave from an amplifier 18 is fed to coupled tuned circuits 28, the primary and secondary circuits being connected respectively across horizontal and vertical deflecting electrodes 8, 81; 9, 9<SP>1</SP> in the beam deflection tube 1. The detected output signal is taken at 14 from quadrant-shaped collector electrodes 10, 11 connected jointly to a load resistor 12. Owing to the phase shift produced at 28 varying with the frequency, the path traced by the beam on the collector electrodes varies from a circular path at mid-frequency, through elliptical paths of increasing eccentricity, to linear paths directed at 45 to the horizontal. The period during which the beam strikes the electrodes 10, 11, and thereby contributes to the output voltage at 14, is thus dependent on frequency deviation. The electrodes 10, 11 are backed by conductive sectors 16<SP>1</SP>, 16<SP>11</SP> divided on a vertical diameter, and connected respectively through resistors 38, 39 to feed back slow voltage changes to the deflecting plates 8, 81; and the collecting electrodes 10, 11 are similarly connected through other resistors 42, 43 to the plates 9, 9<SP>1</SP>. In this way the beam is accurately centred when no carrier wave is applied.
